Abstract

The invention relates to novel hardwood manufactured based on a compaction technology. The hardness of the novel hardwood is 5-9H, the surface of the hardwood is a mirror surface or a frosted surface, and the hardwood is manufactured by the compaction technology including softwood pretreatment, high-temperature high-pressure treatment, pressure continuing treatment, high-temperature treatment under reduced pressure, and constant-pressure maintaining treatment at reduced temperature. The manufactured hardwood is resistant to high temperature and boiling, is hard and wearable, has good surface glossiness, is not required to be painted, paint-sprayed or treated with other processes when used for manufacturing a wood product, and is an environment-friendly product.

Description

technical field [0001] The invention relates to a kind of hardwood, in particular to a novel hardwood made based on compaction technology. Background technique [0002] At present, my country is a big country in the manufacture of wood products in the world today. The raw materials of the required wood are almost imported. Among the imported wood raw materials, the proportion of hardwood is greater than that of softwood (usually softwood is called softwood, such as pine, fir, etc. ; The broad-leaved wood is called hardwood, such as oak, maple, ash, etc.). Hardwood is firm but grows slowly, and has a fine and compact wood structure. Generally, such wood has a large proportion. These woods are hard and dense, with gorgeous color and delicate patterns. They are excellent materials for making furniture and wood products, so the price is very expensive, while cork is composed of many flat cells arranged radially. The cell cavity often contains resin and tannin compounds, the cel...
